| 摘 要： | 以铁尾矿多孔陶瓷为载体,通过自发浸渗法成功制备出了添加石墨烯的复合相变储能材料,并对该材料热学性能及稳定性进行测试。结果表明:通过改变载体孔隙率,可以制得导热系数为0.41~0.59 W/(m·K)、潜热为69~120 kJ/kg、热学稳定性良好的导热增强复合相变储能材料。通过拟合,复合相变储能材料的导热系数与多孔载体的孔隙率呈线性关系,且经100次热循环后材料熔化潜热和导热系数分别降低了3.2%和16.7%。本研究为固废铁尾矿在蓄热、储能领域的应用提供了新思路。

| Abstract: | Thermal enhanced composite phase change materials for energy storage (TCPCMs) were fabricated by the spontaneous infiltration treatment, with adding graphene and iron tailing porous ceramics as the carrier. Based on the tests of thermal properties and stability, TCPCMs with thermal conductivity of 0.41~0.59 W/(m·K), latent heat of 69~120 kJ/kg, and good stability are obtained by adjusting the porosity of the carrier. Thethermal conductivity of TCPCMs has a linear relationship to the porosity of ceramic carrier by fitting test data. Besides, the latent heat and thermal conductivity of TCPCMs decrease by 3.2% and 16.7% after 100 times melting/solidification cycles. This research provides a new idea for the application of solid iron tailings in thermal and energy storage materials. |
